ASTON KHT PISTON SEAL

    KHT PISTON SEAL
    – A dynamic seal which, thanks to the particular profile, improves the distribution of the pressure and drastically reduces friction. It is made up of a special high polymer resistance whose mechanical properties are a combination of the fl exibility of elastomers and the resistance of thermoplastics technicians.
    – A standard low deformation O-Ring permanent as an energizing element on the static part
